The symbol used by the United Methodist Church has been the official insignia of The United Methodist Church since 1968, when the Evangelical United Brethren joined the Methodist Church. The two tongues of the flame represent the union of these two denominations and this church is currently the third largest Christian denomination in the United States.
The Baptismal Cross is a Greek Cross superimposed on an 'X' (Greek: chi). This chi is the first letter of the Greek word for Christ. It was used in ancient Egypt as a symbol of the Ogdoad, the primeval forces of chaos in Egyptian mythology, represented as eight deities which existed before the creation of the sun god.
Four arrowheads indicating the spread of power or influence to all lands.
Four barbed spears, indicative of the fisherman, also giving the sense of rotation or progression.
In this symbol, the three steps leading up to the cross represent the mound at Calvary or, more often, in descending order they represent Faith, based upon Hope, based upon Love.
A sign appeared to the Roman Emperor Constantine as a light in the noon-day sky. At the same time, he heard the words, In Hoc Signo Vinces (In this sign you shall conquer).
The Consecration Cross also called a Rounded Cross. The arms are splayed like paws (known in heraldry as pattee).
The Greek Cross usually suggests the Church of Christ rather than a symbol of Christ's suffering. It appears as a 'plus sign' in liturgical documents to indicate where the priest should make the Sign of the Cross. (For example "The peace + of the Lord be + always with + you.")
The Basque Cross shape is called a Lauburu, an ancient symbol of prosperity. In the Basque language lau-buru means 'four mountain peaks' and it is possible this term gave rise to the name of Labarum.
This symbol features steps, degrees, grieces, or the French: à degrés, like the steps of an ancient pyramid. These steps could be on just the lower part, or on all four arms as shown here. Such a cross is referred to as a Degraded Cross, Graded Cross or Croix Peronnée. There are often four steps and sometimes number as many as eight, diminishing in size as they ascend toward the center.
The Sun Cross features a circle around a cross. It is an ancient symbol; carvings of which were found in 1980 on the bases of Bronze-age burial urns at Southworth Hall Barrow, Croft, Cheshire, England and the urns date back to circa 1440 BC.
This is a classic Druid Symbol and although it is similar to the Baptismal Cross, to call Taranis a 'cross' is a misnomer - it's a circle with spokes and represents a wheel. And the circle of the Taranis Wheel does not represent the Sun. Far from it; Taranis was the Celtic god of thunder and he used this wheel to generate lightning. As the wheel rotates on the cosmic axis, it generates sparks as it spins and we see these sparks as lightning.
